LoRa – Device Re-activation Call Flow (Rejoin Procedure)
LoRa Technology supports the handling and configuration of rejoin-requests for LoRa End Devices. Using a rejoin-request, a device is able to request the network-server to re-activate, without being ‘disconnected’ until […]
LoRa – Device Activation Call Flow (Join Procedure) using OTAA and ABP
When a new End Device (LoRa Device) is added to a LoRa network, it should go through an activation process. Through the activation process, both session keys are shared between the […]
LoRa- (Long Range) Network and Protocol Architecture with Its Frame Structure
LoRa is Long Range ,low data rate, low power wireless platform technology for building IoT network. It uses unlicensed radio spectrum in the Industrial, Scientific and Medical (ISM) bands to enable communication between […]
Narrow Band-IOT UE Attach Call Flow Messaging
When a NB-IOT UE accesses a cell, it follows the same principle as for LTE: It first searches a cell on an appropriate frequency. Decode NPSS and NSSS for NCellID. […]
Narrow Band Synchronization Signals (NPSS and NSSS)
The NPSS and NSSS helps UE to synchronize downlink to an NB-IoT cell. These are transmitted in certain subframes based on an 80-ms repetition interval. By synchronizing to NPSS and […]

Accent Systems introduces its new LTE device. It’s an IoT tracker with LTE and beacon technologies, designed to get maximum efficiency and precision in indoor and outdoor locations. It allows you to […]
Citizens Broadband Radio Service (CBRS), Frequency Spectrum, Operation Modes and Its Applications
Citizens Broadband Radio Service (CBRS) is a 150 MHz wide broadcast band in 3.5 GHz band starting from 3550 MHz to 3700 MHz. The Federal Communications Commission (FCC) regulates interstate and international communications by radio, […]
Citizens Broadband Radio Service Device(CBSD), Its Types and OEMs
Citizens Broadband Radio Service Device(CBSD): As per FCC, an eNodeB which is capable to support CBRS band is referred as Citizens Broadband Radio Service Device. LTE band B42 and B43 […]
Maximum Coupling Loss (MCL) and Maximum Path Loss (MPL)
Maximum Coupling Loss has been chosen by 3GPP as the metric to evaluate coverage of a radio access technology. In theory, it can be defined as the maximum loss in […]
Cat. NB1 and Cat. NB2 Devices Comparison
Narrow Band IoT specifications was first introduced in 3GPP release 13 and then further enhanced in 3GPP release 14 with some essential features. Release 13 NB-IoT device category is referred […]
